begin several years before visible construction starts. NATCA representatives should work collaborat ively with facility management to ensure that the ATO is ready for whatever impact may come. o The ACAC did not meet this week. RNAV and PERFORMANCE BASED NAVIGATION (PBN): Dennis Kelly (PHL) is NATCA's Article 48 Representative working the criteria f or RNAV and PBN procedures. Mr. Kelly's update for the membership is next. · ASR removal – This is a new offshoot of procedure removal process that will probably become part of National Procedure Assessment (NPA). o AJV - 5 revealed that of the 200 plus ASRs, 100 are not DoD so are they being used? DoD says they are required to have the ASRs. o Nobody seems to know and if there is even requirement anymore to run or use them. o Civil airports may want to keep the procedures on the books for traffic count purposes. · NPA – Here is a breakdown of the number and types of procedures that have to be maintained by AJV - 5, which gives you an idea of why so much money is spent on maintenance as each procedure or line of minimum need to be che cked every 18 - 24 months. o Number of procedures (from FAA website on inventory summary) § SIDS 2100 6% § STARs 670 (520 Conv. 358 RNAV) § 2%, RNAV approaches 13,691 40% (LNAV, VNAV, LPV, LP GPS stand alone) § RNAV (RNP) 720 2%, ILS 1745 5% § LOC 14 98 4% § NDB 694 2% § TACAN 15 .04% § VOR 2164 2% § LDA 33 .1% § ASR 221 1% § GLS 11 .03% § PAR 7 .02% § SDF 6 .02% § Circling 10,647 31% § Side Step 83 .02% § out of scope – ODPs 137, RNP Specials 4, VOR/DME RNAV 6. o The SID numbers are inflated because many serve many airports and they are counted as individual procedures because each initial segment needs to be evaluated. STARs that serve multiple airports aren't the same because the inbound portion to the airports has already been eva luated whether it connects to an approach or a radar vector, which doesn't need an evaluation. Circling minimums can be deceiving as well because some are the same as other minimums or serve multiple procedures. · Costs per year: Flight inspecti on is $626 per procedure. Cost is the same regardless of type approach and is .33 hours per IFP. Average time to check RNAV procedures is 18 months. IFP average maintenance cost per line of
